Hello:
Occasionally I experience long, 40-50 secs hangup in my openSUSE 13.1 system. Following such hangup dmesg output contains the following lines at the end:

Either one of the disks is bad or the motherboard has problem.
How can I identify which disk is, or which SATA link/connector is the indicated ata1.00 device?
What is/are the exact meaning of the above dmesg error messages?
Thanks in advance,
Istvan
Hi Istvan, You can invoke dmesg and pipe it to grep to see just the lines containing 'ata1'. Here's one line from my output identifying the device: carlh:~> dmesg | grep ata1 8< - - - - - trimmed - - - - ->8 ***** [ 2.215271] ata1.00: ATA-9: Samsung SSD 840 PRO Series, DXM06B0Q, max UDMA/133 ***** 8< - - - - - trimmed - - - - ->8 This line from your output is concerning:
[ 6538.030599] ata1.00: device reported invalid CHS sector 0
Did you confirm when you installed that your BIOS was set to use LBA (Logical Block Addressing) or CHS (Cylinder - Head - Sector) addressing (possibly with LBA > CHS translation?) You should check the manufacturer's setup and BIOS instructions for your motherboard - both in the user guide and on their website and confirm which method this hard drive was originally configured to use. Also see: https://en.wikipedia.org/wiki/Logical_block_addressing and https://en.wikipedia.org/wiki/Cylinder-head-sector in addition to querying smartctl for the status of the drive's health. hth & regards, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
